Re: How to attach strip of foundation to frames
That would seem reasonable Joseph as the hot melt does not actually penetrate the timber just sits on the surface. So moisture would undermine it.
However, for my mating nucs which are natural comb, I attach wax foundation strips with hot melt glue, actually faster than using melted wax. Maybe the glue fails in time I don't know. But it does last long enough for the bees to build comb and get it attached in it's own right, so even if the glue fails the comb is still attached. I only use a few small drops of glue so the bees can attach most of the comb direct to the timber without relying on the glue, just in case it eventually fails.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
